Buildings.Templates.Components.Validation.Coils
Validation model for coil components
Information
This model validates the models within Buildings.Templates.Components.Coils by exposing them to a fixed pressure difference on the air side. Models representing a water-based coil with valve are also exposed to a fixed pressure difference on the water side, and a varying valve opening from fully closed to fully open position. Other coil models are controlled with a signal varying from 0 to 1.
